This invention relates to an improved process of and apparatus for the manufacture of artificial silk and analogous products.

In the treatment of artificial silk thread many methods and apparatus have been devised to subject the thread to various treating liquids and Sugdrying mediums without injury thereto. gestions have been made to guide artificial filaments in a helical path over discs and the like which partially or entirely dip into treating baths. Ithas also been suggested that the artificial filaments be guided over rotating reels so constructed 'as to advance the filaments in an axial direction while spraying the filaments with the desired treating liquid.

One object of this invention is to provide an improved process for the after treatment of artificial silk, wherein a plurality of groups of artificial filaments .are advanced together substantially in a helical path over the surface of a rotating cylinder;

Another object of this invention is to provide an improved process of and apparatus for the after treatment of artificial silk filaments whereby an equal and uniform treatment of the filaments may be had.

A further object of this invention is to provide an improved arrangement for the handling of artificial silk filaments whereby the treating liquids will be sprayed on or contacted with the filaments travelling in a substantially helical path.

These and other objects of our present invention will become more apparent from a study of the following description and by reference to the attached drawings in which:

Figure 1 shows a vertically positioned cylinder provided with a suitable source of liquid which directs the liquid tangentially against the cylindegm e 2 is a view in side elevation of a pair of horizontally disposed rollers provided with means for supplying compressed air thereto;

Figure 6 is a side elevation of a modified form of treating apparatus;

Figure 7 is an end elevation thereof; Figure 8 is a top plan view thereof; I Figure 9 is a top plan view of the lower roller showing the wiping arrangement;

' Figure 10 is a detailed view of one of the wipers;

Figure 11 is a side elevation of still another modified form of the invention; Figure 12 is an end elevation thereof; and- Figure 13 is a view showing a roller in a slanting position and provided with a spray device. 5

Referring now to the drawings and more par'-' I ticularly to Figure 1, there is shown a vertically positioned roller I, supported by a shaft 2 journalled in the bearing 3. The liquid is sprayed on the roller tangentially thereto by means ofa 10 supply pipe 5 located adjacent the'top of the roller. The liquid mov es downwardly on the roller in a steeper and steeper path gradually increasing in width and drips from the edge 4 of the roller into a ring shaped vat or receiver t. 15 As. will be noted this receiver is provided with a pipe 2! to draw of! the used treating liquids. The filament 22 moves along the surface of the roller in a helical path and the different windings are maintained at a uniform distance from each so other, by the bar 23 carrying hooks 24 over which each winding is passed.

In Figures 2-5 inclusive, there is shown a modified form of apparatus in which a pair of cylindrical rollers 25 and 26 are provided for the g5 advance of the thread. The liquid supplied by the pipe lines 21 and 28 to the surface of the lower roller 28 has a tendency, because of the gravitational force exerted thereon, to flow downwardly. This tendency. is overcome by the useo of compressed air supplied throughthe pipe 2! which will force the liquid along the surface of the roller in an axial direction. The resultant of the movements of the liquids causes the liquid to fiow in a substantially helical path.

In accordance with the modification disclosed in Figures 6-10 inclusive, two'wiping blades or members 30 and 30' are arranged between the upper and lower rollers 2| and 32 and adjacent the. said lower roller, and in a slanting position with respect thereto. The wiping edge of each blade is provided with a plurality of openings or teeth 33. Two difierent liquids are fed uponithe' lower rollers by pipe lines 34 and 35. Because of the slanting position of the blades with respect to the lower roller, the liquids will be moved toward the right hand edge of the roller upon the rotation of the said roller in the direction of the arrow "41. 7

An additional blade 36 positioned between the blades 30 and 30' serves to prevent the comingling of the treating liquids used. In operation the liquids are gradually moved along the "surface of the roller passing through the teeth formed in the blades: the liquid will flow through I one of the openings in the, blade and is again taken up and advanced through the next opening after a renewed dispersion on the rollers.

In Figures 11 and 12, there is shown apair of cylinders 31 and 38' provided with a plurality of helical grooves 39. The treating liquids are supplied to the cylinder 18 through pipe lines 40 and ll. Because of the helical grooves the liquid is advanced from one end of the cylinder 38 to the other, inv this instance from left to right due to the rotation of the cylinders as indicated by the arrow "1). A change in the direction of rotation of the cylinders, or a change of the helical paths of the grooves, will, naturally. result in a change of direction of the advance of the liquids.

In Figure 13, there is shown a still further modified form of the invention. A cylinder 42 is supported by'the shaft 43, journalled in the bearing 44, in an inclined position. The liquid drips or fiows on the cylinder from the pipe I! and moves in a helical path uponthegotation of the cylinder toward the lower edge 46. The used liquid is collected in the vat 41 and led ofi through the pipe 40. A guide bar 49 is provided with hooks II which maintain the thread ii in a uniform helical path.

From the above description it will be appreciated that many changes may be madein the construction of. the device without in any way departing from the spirit or scope of the invention. Accordingly, the invention is to be limited, only by the scope of the following claims taken in view of the prior art.
